>> What is Java's equivalent of Xamarin or Avalonia?

Xamarin - RoboVM was a Java-based competitor to Xamarin which Xamarin acquired in 2015, but it was shutdown in 2017 after Microsoft acquired Xamarin. There are some Java-based toolkits such as https://www.codenameone.com/ that target mobile, but they are probably not as well funded as Xamarin has been under Microsoft. From what I hear Xamarin will be deprecated and replaced by MAUI.

Avalonia - Java has had multiplatform windowing for much longer than C# has. The Java Swing toolkit has been part of Java for more than a decade and is still supported in OpenJDK. JavaFX (https://openjfx.io/) is a newer toolkit that was originally part of Java and was later spun out into its own project.

How well are Xamarin and Avalonia supported if you are doing C# development on Mac or Linux?

>> How do I run Java on iOS?

As stated above, some tools such as https://www.codenameone.com/ and https://github.com/google/j2objc that convert Java code to target iOS.

I have never tried using those tools so I am not sure how good they are.

One, I don't understand Java environments really well. All I have done so far is create some GUI applications using JavaFX. Wish I could share my code, but unfortunately, its part of my assignments and can't be open-sourced. Second, the instructions I found in the Contributing docs were bare-minimum, and kinda hard to follow for a beginner. An experienced Java developer would get them really quickly, no doubt about that.

JavaFX (an open source, next generation client application platform for desktop, mobile and embedded systems) has many useful out the box UI controls to build modern interactive desktop apps. These include buttons, checkboxes, list views, labels etc, that can be configured and styled in countless ways. I’ve using them for many years at work building mapping apps!

As I'm typing this, I'm realizing that the 4 part webinar actually sets up a lot of it. By this point, you should have installed: your IDE (I used intellliJ), the Java SDK, downloaded the JavaFX file here(that you'll manually add into your project structure), and the MySQL connector J file.

JavaFX works well with Kotlin if you're looking for an imperative toolkit. Just add this plugin in your build.gradle to import it.

You could also download the JavaFX modules separately from https://openjfx.io/
